Last period was on August 13. They ALWAYS last 6 days. I did have sex quite a bit before during and after Ovulation. 2 days ago (as Glow predicted) I started my period. Cramps were so bad I had to lay down. Now, since Tuesday my period is getting lighter, it’s brown and I’m only spotting. What the heck is going on???
